Health Benefits Of Durian

Durian is a large, spikey fruit with a rich content of phytonutrients, antioxidants, proteins, vitamins and minerals. The term ‘durian’ has been derived from the Malay word ‘duri’, which means thorn. 
 
Durian is delicious, soft and succulent with a distinctive sulfuric smell and is covered with formidable thorn husk. It is characterized by the rich, buttery smooth and luscious flesh that is finger-licking delicious. 
 
Also known as the “King of Fruits” in the Southeast Asian countries, durian boasts of numerous health promoting effects. Native to Brunei, Indonesia and Malaysia, this exotic fruit is 30 cm long and 15 cm wide and weighs around 1 to 3 kg. 
 
Today, the fruit is cultivated in Thailand, India, Sri Lanka, Vietnam, Papua New Guinea, southern Philippines and other Asian countries. The shape can range from oblong to round. While the husk color is green to brown, flesh is mostly pale yellow to red, depending upon the species. Just like banana and jack fruit, durian is rich in energy, vitamins and minerals. Read on to know the health and nutrition benefits of eating durian. Also explore its nutritional value.

Demand for Durian: the medicinal fruit

About 550 people from various parts of Southern India have placed their orders to buy and taste the rare Durian Fruit, which has medicinal value, with Tamil Nadu State Horticultural Department, growing this rare tree at Kallar and Barliyar Horticultural farms in Nilgiris district of Tamil Nadu.

People believe that the fruit is the anti-dote to infertility.

This leads to high demand for it every year. In the southern states, the demand is for the spiny variety.
The fruit is believed to possess medicinal qualities and increase a woman's estrogen hormone production, enabling her to conceive.

Drian, botanically called as ''Durio Zebittheinus'' will start yieling fruits in the next 15 days from 33 trees after being planted. The fruit will be sold Rs 300 per kg this year as against Rs 230 per kg last year. The season for this will be July to September every year.

Last year, they had sold the fruit to about 400 people from a total production of 1127 kg. The yield was 1540 kgs during 2006-07.

This year, they expect an yield about 1500 kgs from the two farms, B Ramakrishnan, Assistant Director, Horticultural Department told UNI.

He said once the fruit is picked from the tree, it should be consumed within two to three days. Each fruit weighs between one to two kgs.

It is also said to be rich in carbohydrates, proteins and fats.

Under its hardy shell are sections of pale yellow flesh with a consistency that can be as soft and oozy as custard, along with a flavour that is nutty and sweet with hints of vanilla and an occasional bitter taste.
The traders of Durian in the markets are receiving good response from the public even though it is costly, said Vinayakam, a trader here.

He Said ''Durian has good medical benefits and is rare to get. Though it is costly, ''I buy them every year because it has good medicinal benefit and is also good to market.'' Durian tree is native to South East Asia, primarily Sumatra and Borneo. But it could easily be transplanted in equatorial Africa, equatorial Central America, or Southern United States.

Durian and Cholesterol

The Cholesterol Content of Durian

Is durian high in cholesterol? No. This part is simple: durian does not contain cholesterol. None at all. The USDA National Nutrient Database lists any amount of durian as containing 0.0 mg of cholesterol. For those familiar with basic nutrition or biology this should come as no surprise since no plants contain cholesterol. So, durian doesn't have any cholesterol and neither does any other fruit or vegetable.

Dietary Fat Influences Cholesterol Levels

Durian is not off the hook just yet, though, because even without containing cholesterol food can affect a person's blood cholesterol levels. Dietary fat has an influence on the amount and type of cholesterol circulating in our arteries. The scientific community has conflicting opinions on the details of this relationship, but the majority of evidence seems to indicate that increased dietary fat intake results in increased blood cholesterol levels (within a range).

Durian, with an average of 30 percent of calories coming from fat, is a fatty fruit, but does eating it increase your fat intake (and therefore your cholesterol)?  The answer is 'yes' if the alternative is a handful of bananas, plain rice, or a plain potato, but more common meals like fried rice with chicken, a baked potato with butter, or macaroni and cheese, are all likely to contain more fat per serving than durian. For comparison, 72 percent of calories in cheddar cheese are from fat and even a glass of 2% reduced fat milk provides 35 percent of its calories from fat.

Not that all of this fat is necessarily a bad thing. Cholesterol is vital to good health. While you don't want your cholesterol levels to be too high, extremely low cholesterol leads to its own set of problems. Eating a moderate amount of fat can help to keep your cholesterol in the healthy range, between 160 and 200 mg/dL.
Total blood cholesterol is, however, only part of the story. Perhaps more important for cardiovascular health are the amounts of high density lipoprotein (HDL) and low density lipoprotein (LDL) circulating in your blood. HDL is known as 'good' cholesterol, and LDL is commonly regarded as 'bad.' Most people with cholesterol issues will benefit from lowering LDL and increasing HDL. How do you do that?

Improving Cholesterol Levels

Here's the mainstream medical advice for achieving healthy cholesterol levels:
  • Exerise regularly – Opening a durian is exercise.
  • Maintain a healthy weight – Skip the all-you-can-eat durian buffet?
  • Avoid trans fats – Not a problem. Don't deep fry your durian.
  • Limit saturated fats  – Unfortunately, this one might apply.
Most medical and public health literature advises us to limit our consumption of fats and especially of saturated fats which are accused of causing a rise in total cholesterol. My research into the relationship between dietary saturated fat and cholesterol levels has not lead me to easy conclusions. It is a complicated subject, and one on which many disagree. I will attempt to paint a picture of the complexities while respecting the prevailing precautionary recommendation.

It is worth considering the difficulty of establishing the relationship between serum cholesterol and any one nutrient. To reduce saturated fat intake without reducing total calories requires increasing some other nutrient, so it is not possible to claim that limiting saturated fats reduces serum cholesterol without considering the substitute (or otherwise showing the effect wasn't the result of reduced total calories).

A meta-analysis of 60 controlled trials found that replacing saturated fats with carbohydrates did little to improve the total to HDL ratio, while replacing saturated fat with unsaturated fats (cis, of course, not trans) did show significant improvements. 

The same study also found that while lauric acid, a saturated fat, increased total cholesterol, it achieved this mostly through an increase of HDL, the 'good' cholesterol. Lauric acid is not especially prevalent in durian, but this finding does suggest the current stance against saturated fat deserves further consideration.

The standard advice shouldn't be casually disregarded, but there is a growing field of researchers who disagree with the commonly held belief that saturated fat causes unhealthy cholesterol levels. These thinkers also tend to question the causal relationship between cholesterol levels and heart disease, citing the greater positive correlation of other conditions such as inflammation. If you want to learn a great deal more, consider my recommended reading list below.

Until the evidence is sufficient to persuade the majority to rewrite the books, it may be prudent to limit most dietary saturated fats and when necessary reduce their intake by substituting with monounsaturated and polyunsaturated fats. With that in mind, let's take a look at the saturated fat content of durian and how the king of fruits can fit into a healthy diet.

The Fat of the Matter

The fatty acid composition of durian is different for each variety, but there are enough similarities to draw a general picture. The USDA lacks detailed data on the breakdown of durian's fat, but an independent study analyzing the fatty acid content of four Malaysian cultivars (D-24, D-2, D-8, D-66) found a fair amount of saturated fat, between 58 and 65 percent of total fat (Berry, 1981).

That's high compared to well-known sources of monounsaturated fat like olive oil, which is only 14 percent saturated, and almonds (7%), but still lower than butter (68%), and coconut oil (86%). Of course, only 5 percent of a durian is fat; almonds are 49 percent, butter 51 percent, and olive oil and coconut oil are 100 percent fat. Point being you can eat considerably more (10 to 20 times more!) durian and consume the same amount of saturated fat found in a lesser amount of these higher fat foods.
The American Heart Association recommends limiting saturated fat to 7 percent of daily calories. The USDA Center for Nutrition Policy and Promotion suggests limiting saturated fat to 10 percent of daily calories. On a 2000 calorie diet, 7 percent allows 16 grams, and 10 percent allows 22 grams of saturated fat. To reach 16 grams you would have to eat about 450 grams of durian. Monthong, one of the fleshiest durians, is 30 percent edible. If we use that figure (which is on the high end to be safe), we will find 450 edible grams in a 1.5 kg durian. The 10% mark of 22 grams saturated fat is found in 2.0kg of durian, by this same estimation.

Conclusions

Luckily, it seems the recommendations for achieving healthy cholesterol levels do not preclude eating durian. They may, however, indicate moderation of durian consumption is wise for people with existing cholesterol issues. For the rest of us, I think it is probably safe to pig out.

If your diet is otherwise low in saturated fat, you can safely eat a 1.5 to 2.0 kilogram durian, even the fleshiest varieties with the highest saturated fat, every single day and fall within the guidelines for a heart healthy diet.

Durian - King of Fruits


One of its own kinds, Durian fruit is delicious, soft, succulent and very popular for its unique characteristics. Durian is widely revered as the "King of Fruits" in the South-East Asian countries.

The tree is tropical in origin and belongs to the genus Durio, family of Malvaceae; a large family of plant species which also include hibiscus, okra etc. It is botanically known as Durio zibethinus.

The exotic durian is native to Brunei, Indonesia and Malaysia. While there are 30 known species of Durio exist only nine of them have been identified as producing edible fruits. Durian tree starts bearing fruits after four or five years after plantation. The tree grows up to 50 meters in height depending on the species.

Durian is a seasonal fruit; its season lasts typically from June till August, which coincides with that of the other tropical specific fruits like mangosteen, jack fruit, and mango.

The fruit is distinctive for its large size, unique odor, and formidable thorn-covered husk. It can reach up to 30 cm (12 in) long and 15 cm (6 in) in diameter, and typically weighs one to four kilograms (2 to 7 lb). Shape wise, it varies from round to oblong; color of its husk (rind) is green to brown; and its flesh has creamy-yellow to saffron color depending on the species.

The flesh or pulp can be consumed at various stages of ripeness, and is used as flavor base in a wide variety of culinary and sweet preparations in Southeast Asian cuisines. Round to oval shaped seeds can also be eaten when cooked and tastes like almonds.

Edible flesh emits distinctive odor which can be described as strong and penetrating even when the husk is intact; this unusual stinky flavor and intense odor of the fruit have prompted many people to express diverse and peculiar opinions ranging from deep appreciation to intense disgust about durian.

Health benefits of Durian fruit

Durian fruit, like Banana, avocado and jack fruit, is rich in energy, minerals and vitamins.

The fruit is made of soft, easily digestible flesh with simple sugars like fructose and sucrose and some amount of simple fats that when eaten replenishes energy and revitalizes the body instantly; can be used as supplement food in the treatment plan for underweight children. Although it contains a relatively high amount of fats among fruits, but it is free from cholesterol.

Durian is rich in dietary fiber, which makes it a good bulk laxative. The fiber content helps to protect the colon mucous membrane by decreasing exposure time and as well as binding to cancer causing chemicals in the colon.

Durian fruit is a good source of antioxidant vitamin-C (about 33% of RDA). Consumption of foods rich in vitamin C helps body develop resistance against infectious agents and scavenge harmful free radicals.

The fruit is an excellent source of many health benefiting B-complex groups of vitamins; a rare feature among fruits, such as niacin, riboflavin, pantothenic acid (vitamin B5), pyridoxine (vitamin B-6) and thiamin (vitamin B-1). These vitamins are essential in the sense that body requires them from external sources to replenish.

It also contain good amount of minerals like manganese, copper, iron and magnesium. Manganese is used by the body as a co-factor for the antioxidant enzyme superoxide dismutase. Copper is required in the production of red blood cells. Iron is required for red blood cell formation. Fresh durian fruit is a very rich source of potassium. Potassium in an important electrolyte of cell and body fluids that helps controlling heart rate and blood pressure.

It also contains high levels of essential amino acid, tryptophan (also known as "nature's sleeping pill") which in the body metabolizes into serotonin and melatonin; these neuro-chemicals have an important functions like sleep induction and in the treatment of epilepsy.

Selection and storage

The durian fruit is native to Southeast Asia. It is sold in markets all over the Asian world and is also imported in the United States and Europe. People have differences in preferences regarding ripeness, while some like slightly ripened, tart flavored durians while others might like to cherish over ripened. Usually, ripe fruit that falls off the tree is collected and put to sale.

In the store, choose a durian fruit with firm stalk. It is one of the expensive fruit; some of its varieties like D24 (Sultan) is in high demand and commands higher price. The fruit can also be stored in the refrigerator for few days.

Preparation and serving methods

Outer surface of the Durian fruit is fully covered with sharp thorn like spikes, capable of causing cuts; it is therefore, one should be careful while handling it. Cut open the fruit longitudinally the same way you do in Jackfruits to expose underlying creamy yellow pulp. Slice the pulp to remove seeds.

Here are some serving tips:

Durian fruit is used as a flavor base in a wide variety of sweet edibles such as traditional Malay candy, ice kachang, dodol, rose biscuits etc.

It is also used in the preparation of ice-cream, milkshakes, Yule logs and cappuccino.

Red-fleshed durian is traditionally added to sayur, an Indonesian soup made from fresh water fish.

Ikan brengkes, a fish cooked in a durian-based sauce, traditional in Sumatran islands in Indonesia.

Unripe durians may be cooked as a vegetable in variety of dishes. Durian seeds which taste similar to jack fruit seeds or yam can be eaten boiled or roasted.

Benefits Of Durian

Durian is a fruit abundantly found in Southeast Asian countries and is commonly known as the king of fruits. People who just se and smell this fruit immediately get repelled by its strong and pungent odor. Only those brave people who are able to taste the fruit even after its offensive smell are able to taste this wonderful fruit. Although the odor of the durian fruit is strong and pervasive, but once a person eats it, he is sure to get addicted to it. Apart from having a great taste durians are highly beneficial for our body. The many benefits of durian include:

1. Provides vitamins to the body.
Durian is highly nutritious as it provides rich amounts of vitamin B, vitamin C and vitamin E to the body. The high iron content of this fruit helps in restoring the health of sick humans and animals.

2. Helps in curing jaundice.
A preparation from the roots and leaves of durian has traditionally been used as medicine for treating various kinds of fevers and jaundice.

3. Lowers cholesterol.
The organosulphur compounds present in durian reduce the synthesis of cholesterol in the liver cells. Intake of the durian fruit aids in lowering blood cholesterol levels.

4. Detoxification of blood.
Regular intake of the durian fruit helps to remove toxins accumulated in the blood. It is therefore, a strong blood cleanser and prevents the occurrence of many diseases.

5. Improves the general well-being.
Durian contains high amounts of amino acids namely tryptophan. This is particularly known to alleviate symptoms of insomnia, anxiety and depression. It also helps in raising the levels of serotonin found in the brain, which makes a person feel well and happy.

6. Helps to build muscles.
Durian contains rich amounts of soft protein and is, therefore, used for building good muscles.

7. Improves sex function.
Durian is known to be a powerful aphrodisiac and is often consumed to improve the sex drive and overall sex function.

8. Anti-inflammatory activity.
Any inflammation in the body causes a risk for cardiovascular diseases. Durian fruit contains Organosulfur compounds that inhibit the action of inflammatory enzymes such as lipoxygenase and cyclooxygenase, thus reducing the risk to any such diseases.

9. Antioxidant Activity.
The organosulfur compounds present in durian have antioxidant activity. Presence of this substance in the body stimulates the production of glutathione, which itself is a vital intracellular antioxidant The durian fruit is extremely nutritious, but it is advised not to consume it in excess. People suffering from high blood pressure and pregnant women should not consume durian as the seeds are toxic in nature and can causes shortness of breath.
